How long will the Singapore Huang Ka Record last?

According to the official records of Singapore Huang Ka, it is two years. When you leave the country, the customs will also tell you that if you want to come to Singapore again in two years, you can write an application to the Immigration Bureau, and if approved, you can also travel to Singapore. But at present, we haven't met anyone who can go to Singapore after winning the yellow card.

After so many years of visa experience in Singapore, you can't go to Singapore without Huang Ka.
